Random Prnt.sc is a fun project that locates random publicly available images stored on Prnt.sc. Due to cross-origin resource sharing constraints, each random image opens in a new browser tab rather than being embedded directly on the page. Opening too many images in quick succession may result in the user's IP being blocked from accessing Prnt.sc, with 5 images at once identified as a safe limit.
